The effect of MUFA on Coronary Heart Disease (CHD) events is ambiguous, with some meta-analyses showing increased risk and others showing decreased risk.
While MUFA improves risk factors like blood pressure and lipids, its direct impact on preventing heart attacks is not yet clearly proven in long-term observational studies, so it should be part of a broader healthy diet rather than a standalone cure.
ModerateQualifiesMEDIUM confidence
Data from meta-analyses exploring evidence from long-term prospective cohort studies provide ambiguous results with respect to the effects of MUFA on risk of coronary heart disease (CHD).
Why this rating
Based on conflicting meta-analyses of cohort studies.
